DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to a coffee machine, and more particularly to a coffee machine. m [Prior Art] BACKGROUND OF THE INVENTION A known domestic coffee machine typically includes a lower digester, an upper container, and a vertical conduit connecting the digester to the container. When the coffee maker 10 is placed on a heating source such as a cooker, the temperature and pressure within the digester will increase. In this case, the conduit is adapted to receive pressurized water from the lower cooking, passing the pressurized water through a chamber containing coffee powder (so-called "extraction," step) and subsequently flowing it into the chamber In the upper container, the coffee beverage is thus obtained. 15 These long-known and easy-to-use domestic coffee machines are not without drawbacks. In fact, when the coffee machine is heated and a coffee beverage is produced, the water rising from the conduit The temperature and pressure are not constant. In particular, at low temperatures (about 45-55 ° C) and low pressure (about 0.1-0.2 bar), water begins to rise along the conduit. When the amount of water in the digester decreases, The same heat is supplied by the cookware, and the temperature of the water will increase rapidly. Due to the rapid temperature increase, steam is formed in the digester, so the pressure of the water rising from the digester and along the conduit is also rapidly increased. The water that subsequently passes through the chamber containing the coffee powder will be subjected to high temperature (about 5 200808237 95-100 ° C) and high pressure (about 5 · ΐ · 5 bar). After that, the water level in the s cooker is as small as Catheter level of the catheter At (draught level), the conduit will be filled with high temperature (100-105 ° C) steam in the digester. 5 It has been found that coffee beverages obtained from water below 9〇_95. Better and textured sensory properties than coffee obtained with water that is primarily high temperature steam. ^

Substance. These conditions determine the so-called "over-extraction" step. When the side water pressure and temperature conditions are changed by extraction, the substances released from the coffee powder to the water will also change. Further step-by-step depends on the amount of coffee powder that is best filled in the digester 15 in the water of the suitable chamber, the tightness and the size of the grinding, and the type of heating source used to heat the coffee machine. State and adjustment device. In such known household machines, the extraction conditions are thus strongly dependent on the choices made by the user and are almost unpredictable. [SUMMARY] The purpose of the invention is to design and provide a control. The 豕β' of the delivery system can overcome the shortcomings of the above-mentioned prior art. In particular, the task of the present invention is to provide a coffee machine that can simply control the temperature of the coffee powder during the stroke step.

The position of the normal 7 200808237 is when the coffee machine can be firmly placed on the cookware to prepare the coffee. Non-beverage, or when the upper container can contain the maximum amount of beverage without dew. In the drawings, the coffee machine according to the invention is generally designated as 丨. The coffee machine 1 comprises a digester 2, a collection container 3 and a conduit 4 adapted to fluidly connect the digester 2 and the collection container 3 to each other. According to a particular embodiment, a conduit 4 is placed in the lower region of the digester 2 in connection with the upper region of the collection container 3. A valley to 5 series is formed along the conduit 4, which is adapted to contain coffee powder and 1 〇 It is suitable for avoiding the fluid continuity stop of the catheter 4. The force machine 1 further includes a safety valve 2 arranged between the digester 2 and the external environment. The security read 21 is adapted to take a closed operational configuration and an open operational configuration. When the retort 2 exceeds a predetermined pressure release threshold, the safety valve 21 is suitably changed from the closed configuration to the open configuration. Thus the safety valve 21 properly maintains the digester 2 sealingly closed when the internal pressure value is below the release threshold. Further, the safety barrier 21 is suitably located inside the digester 2 and in fluid communication with the external environment when the internal pressure exceeds the threshold of release. 2. According to a specific embodiment of the present invention, the predetermined release threshold when the safety valve 21 is changed from the closed configuration to the open configuration in terms of the difference in pressure or atmospheric pressure is at 〇·5_〇·7 bar. In the range. Preferably, the release threshold ranges from 0.55 to 0.65 bar for different pressures. More preferably, the release threshold is in the range of (10) bar 8 200808237.

Thus, the delivery control valve 41 is adapted to maintain the opening of the conduit 4 until the pressure and flow rate conditions are such that the digester 2 still has a temperature below 9 〇 95 95 c and is still liquid. Therefore, in the so-called extraction flow state, the delivery control valve 41 is adapted to maintain the opening of the conduit 4. In addition, the delivery control valve 41 is adapted to close the catheter 4, ie to stop the fluid communication between the therapeutic device 2 and the collection container 3, and the water from the cooking 2 reaches a very high temperature along the conduit (1〇〇_ 1〇5〇c), or even before the liquid 15 becomes gaseous. Therefore, in the so-called over-extraction flow state, the delivery control valve 41 appropriately closes the conduit 4. In a reliable and repeatable method, the pressure in the immediately upstream conduit 4 of the delivery control valve 41 has been considered as a parameter which allows us to see the path from extraction to over-extraction. According to one embodiment of the invention, the delivery control valve 41 is responsive to pressure conditions occurring immediately upstream of it. In particular, the delivery control valve 41 transitions from the open configuration to the closed configuration when a predetermined control threshold has been exceeded. When the digester threshold in the digester 2 is reached, the control threshold in the upstream conduit 4 of the valve 41 immediately following 9 200808237 is reached. This flow state allows the extraction step to continue when the pressure within the digester 2 is below the digester threshold. When the pressure in the digester 2 is above the digester threshold, the valve 41 does not have any action and this flow condition will result in an overextraction step. According to a particular embodiment of the invention, the digester threshold of the delivery control valve 41 from the open configuration to the closed configuration is less than or equal to the release threshold. According to a particular embodiment of the invention, the digester threshold ranges between 0.3 and 0.5 bar for different pressures. • Preferably, the digester threshold ranges from 10 0.35 to 0.45 bar for different pressures. More preferably, the digester threshold ranges from 0.38 to 0.42 bar. In accordance with the present invention, the operation of a digester 1 is described with reference to Figures 1-5, which are described below. In the coffee machine described in Figure 1, it is intended to be placed on a heating source such as a cookware. In a known method, the digester 2 comprises an appropriate amount of water and the chamber 5 comprises a suitable amount of ground coffee. The ® pressure in the digester 2 is the same as the atmospheric pressure and is less than the digester threshold and release threshold. Therefore, the safety valve 21 is closed and the delivery control valve 41 is opened. In Fig. 2, a heat source such as a cooker supplies heat to the coffee machine to increase the pressure in the digester 2. The pressure in the digester 2 is above atmospheric pressure but below the digester threshold. Therefore, the relief valve 21 is closed and the delivery control valve 41 is opened. The actuation of the pressure (indicated by the positive arrow) causes the water to flow upward along the conduit 4 (as indicated by the wavy arrow). Therefore, the water becomes a coffee beverage and flows to the collection container 3 through the chamber 5 containing the coffee powder. 10 200808237 The heat outside the third part of the kiss is supplied to the adding machine by a heating source such as a cooker, which increases the amount of ice in the digester 2. The pressure in the digester 2 is = at the digester threshold but below the release threshold. Therefore, both the safety valve 21 and the industrial valve 41 are _. Actuation of the fluid pressure along the conduit (as indicated by Zheng Yishuo) causes the job control 41 to be turned off. The f*(10) water flow is stopped and the pressure in the digester 2 is continuously increased. 10 15 20 At the 4th shot, additional heat is supplied to the machine by a heating source such as a cooker, adding additional pressure to the digester 2. The pressure in the digester 2 is both at the release threshold. Therefore, the safety valve 21 is opened and the conveyance control is read off. Actuation of the fluid pressure along the conduit (by the positive arrow • the delivery control valve 41 is closed. The pressure in the digester breaks the safety chamber 21. The water vapor flow is generated (indicated by the dashed head) through the safe reading U to the external environment, and the pressure in the digester 2 is lowered. In Fig. 5, the coffee machine is prepared as a coffee beverage. The pressure in the digester 2 is equal to atmospheric pressure. The safety valve 21 is closed and the delivery control valve 41 is opened. The π-striped smoked state 2 is empty, and the collection container 3 contains the manufactured coffee beverage. The customer knows that the operation of the chamber (4) (10) allows the water passing through the chamber 5 to be terminated. When the pressure and temperature in the unit 2 are considered to be too high, the value of the value is τ. According to the present invention, the coffee machine 1 controls the production of a coffee beverage to be the most versatile. The water that prevents the temperature and pressure from being excessively licked by the coffee powder can thus obtain a coffee beverage having a monthly improvement in general organoleptic properties. According to the sixth to eighth figures of the present invention For example, the delivery control 11 200808237 valve 41 includes a chimney cap 410 and a slider 411. The chimney cap 410 includes an inner ring relief 413. According to the seventh and eighth In the particular embodiment shown, the inner ring embossment 413 is tapered. Thereby, the inner ring embossment 413 is formed in the form of a fluid that is delivered to the center of the conduit 4. As described herein, In a specific embodiment, the slider 411 is slidably received in the smoke from the cap 410. The slider 411 includes an outer ring embossing member 414. The slider 411 is adapted to slide between two positions. The first position, as described in Fig. 7, the delivery control valve 41 is open. In a first two position, as described in Fig. 8, the delivery control valve 41 is closed. In a position (see Figure 7), an annular passage 415 is left between the inner ring embossing member 413 of the smoulder cap 41 and the rod of the slider, the passage being adapted to allow the coffee beverage to pass through it Flowing along the conduit. According to the specific embodiment of Figures 7 and 8, the inner diameter of the inner ring embossing member 413 15 and the inner ring embossing member 413 There is a slight difference between the outer diameters of the partial rods of the slider 411. According to a specific embodiment, the difference between the radii is less than 2.5 mm, preferably less than 1.5 mm. One is the true width of the annular passage 415 if the slider 4U and the smoke from the cap 41 are absolutely coaxial. This narrow annular channelization allows the state of fluid flow to rise along the conduit and face the ring The flow path 415 is stabilized. The coffee beverage flow is stabilized by the entire circumference of the annular passage. When the control valve 41 is sent through the wheel, a uniform drink is displayed. When the machine is in its normal standard position, due to the weight of the slider 12 200808237 411, it moves to the first position where the delivery control valve 41 is opened. As the pressure within the digester 2 increases, the flow rate and velocity of the fluid facing the annular passage 415 are also increased. Due to the stabilization of the fluid flow in the vicinity of the annular passage 415, an operational driving force is obtained by the same pressure as the pressure of the bottom 416 of the slider 411. When the pressure that presses the bottom 416 of the slider 411 exceeds the control threshold, the operational driving force of the bottom 416 pushes the other force on the slider 411 and moves the latter to the second closed position. When the slider is in the second position (see Fig. 8), the outer yoke 414 of the slider 411 is adjacent to the inner ring embossing member 413 of the chimney cap 410. Thereby, 10 closes the catheter 4. In accordance with a particular embodiment of the present invention, a pad 412 is inserted between the two annular net projections, the pad being vertebral and complementary to the outer ring embossment 414 of the slider 411. form. In another possible embodiment, the pad 412 can be formed with the inner ring embossment 413 / 15 of the soot cap 410, which can have a different shape or be disposed. When provided, a liner 412 made of a soft material is preferably adapted to contact a hot beverage. When the coffee machine is used and the pressure in the digester 2 is above the digester threshold, the force generated by the pressure at the bottom 416 of the slider 411 causes it to pass to a second position where the delivery control valve 41 is closed. In accordance with various possible embodiments of the present invention, the coffee maker further includes a selection device 6 to prevent the delivery control valve 41 from being moved from the open configuration to the closed configuration. According to the specific embodiment of Figures 9 and 10, the upper cover 13 200808237 is applied - a fixed cover 61 - 62 of the coffee machine body forming (such as fixed to the soot cap 410) is placed on the fixed cover 61 can be moved by the spherical projection 63 between the locked position and the unlocked position. 5 When the tab 62 is in the locked position (described in Figure 9, the 62 indicated in Figure 1), it is adapted to limit the movement of the slider 4U. - ^ By restricting the movement of the slider 4U, the tab 62 prevents the transport control from taking a closed configuration, thereby preventing its operation. When the tab 62 is in the unlocked position (the sound indicated in Fig. 1 does not interfere with the movement of the slider 411. 10, the ball-shaped dog-outlet 63 allows us to have two different coffee machines in the present invention. The choice between the operating modes. In the r-type of the collar, the ί-shaped tab 62 prevents the delivery control valve 41 from operating. In this second invention, the coffee machine 1 is the same as the -15. The piece 62 does not affect the fall of the ball feed control valve 41. In this pull type, the (4) ^ 501 machine 1# is operated in the manner described. J, the brother 1-5 figure is according to the η figure For example, a movable cover 64 is applied, for example, to the top of the cover. The cover 64 can be unlocked from the cap in the locked position and when the cover 64 is in the locked position ^ Speed movement.), which is suitable for limiting the movement of the slider 41_彳1^ in the dotted line, the cover 64 is anti-#,,, and order. By restricting the slider, thereby preventing its operation, the closed configuration is adopted, whereby 14 200808237 when the movable cover 64 is in the unlocked position (described in Figures 11 and 11a), it cannot be affected. The movement of the slider 411. Alternatively, the removable cover 64 allows us to choose between two different modes of operation of the coffee machine of the present invention. ... one mode is that the cover 64 prevents the delivery control valve 41 from operating. Here, the coffee machine 1 of the private month is operated in the same manner as the known coffee machine.
